Page Layout ⇒ Unwanted blank frame before title frame

[wgf]

I am using Beamer (Dresden theme) and wanted to remove from the title slide header and footer text but leave the color bars in place. I found a solution in this forum but it has created a new problem. An extra blank frame now precedes the title slide. If I comment-out the line "\renewcommand*\dohead{\rule{0em}{1.5em}}" the blank slide goes away, but then I have the header text.

Code: Select all

\documentclass{beamer}
\usetheme{Dresden}
\usecolortheme{dolphin}

\title[title]{Full Title}
\author[me]{My Full Name}
\institute[BSU]{Big State University}
\date{ }

\begin{document}

\begingroup
\renewcommand*\insertshorttitle{}
\renewcommand*\insertshortauthor{}
\renewcommand*\insertshortinstitute{}
\renewcommand*\dohead{\rule{0em}{1.5em}}
\begin{frame}
  \titlepage
\end{frame}
\endgroup

\section{Section 1}
\begin{frame} {Slide Title 1}
      text text text
\end{frame}

\section{Section 2}
\begin{frame}{Slide Title 2}
	text text text
\end{frame}

\end{document}

This problem appears when using Texmaker and TeXnicCenter, but the blank frame does not appear when I just checked my example. This is my first post here and hope someone has an idea for me.
Thanks.

Found the trick to fix the problem (quite by chance, I might add). In the last rennewcommand line I changed the 0em to -1em and that eliminated the extra blank page before the title page.

Code: Select all

\renewcommand*\dohead{\rule{-1em}{1.45em}
